Traffic is expected to run more smoothly now for drivers in northern Sacramento County after new highway interchange opened today.

The $18 million dollar Elverta Road Interchange project replaces a traffic light on State Route 99 with a bridge over the highway, as well as entry and exit ramps. The interchange is about three miles north of where I-5 splits off from 99 towards Sacramento International Airport.

County Supervisor Phil Serna said it’s something the area has needed for decades.

“This overpass, in addition to our other public works projects intended to improve safety and connectivity, mean a great deal," he said. "In this instance it means that we’re enhancing north/south traffic along State Route 99, but also access east/west, especially as it relates to Sacramento International Airport.”

The project also includes bike lanes and sidewalks along Elverta Road. Serna says this was the last intersection in the county along 99 that needed to be elevated above the highway.

The project was paid for with state bonds and county development fees.
